Specification of Letters Patent.

Patented May 16, 1916.

Application filed June 7, 1912. Serial No. 702,243.

To all whom it may concern:

Be it known that I, James R. MOFFATT,

' a citizen of the United States, residing at Chicago, in the county ofCook, State of Illinois, have invented certain new and usefulImprovements in Sewing-Machines, of which the following is adescription, reference being had to the accompanying drawing and to thefigures of reference marked thereon.

Theinvention relates to new and useful improvements in sewing machines,and more particularly to machines of this character for trimming andcovering a raw edge of fabric.

An object of the invention is to provide stitching mechanism and atrimming mechanism which is located in advance of the stitchingmechanism, together with a binder which is so disposed and constructedas to direct the binding tape to the stitching mechanism after the edgeof the fabric has passed the trimming mechanism, whereby the cut edgemay be covered by the binding and stitched to the fabric. I

A further object of the invention is to provide a mechanism of the abovecharacter with devices for supporting the binding guide, so that saidbinding guide may be adjusted in various directions relative to thestitching mechanism, so as to properly direct the binding strip to thefabric.

A further object consists in providing a mechanism of the abovecharacter, wherein the binding guide is so shaped and positioned as toreceive a binding strip from the rear of the machine, fold said strip,invert the folded strip and direct the same about the edges of thefabric to be bound.

A further object of the invention is to provide a mechanism of the abovecharacter, wherein the trimming device includes a movable trimming bladesupported from the tion,Figu re l is a rear view of a sewing machinehaving my improvements applied thereto; Fig. 2 is a plan view of thework plate and the parts adjacent thereto, certain of the parts of themachine being in section; Fig. 3 is a perspective view showing on anenlarged scale the work support, the lower trimming member, the bindingguide and the means for supporting the same; Fig. A is a perspectiveview of the binding guide and the bracket to which the same is secured,the parts being detached; Fig. 5 is a view showing the arm to which thebracket for the binding guide is attached, and the supporting plate forthe arm, together with the means for attaching the parts together,

.said parts being separated; Fig. 6 is a plan view of the work support,showing the position of the binder and the trimmer relative to thestitching point, also showing in dotted lines the fabric being trimmedand the binding strip; and Fig. 7 is a view in side elevation and partlyin section, showing the relation of the trimming mechanism, thedeflector for the trimmed-off strip, the presser foot, the needle andthe binding guide. Fig. 8 is a sectional view through the binding guide.

The machine as herein shown, consists of a work support 1 on which ismounted a standard 2, carrying an overhanging arm 3. The needle bar 4:reciprocates'in the forward end of the overhanging arm, and carries aneedle 5. The material being stitched passes over the work support 6,and is fed to the needle through the usual feeding mechanism, whichincludes a feed dog 7. The material is held on the work support by apresser foot 8, which is carried by the presser bar 9, mounted in theoverhanging arm.

The present machine is especially designed for trimming the raw edge ofa fabric and the covering of the same with a binding bearings 13 andlet, carried by the overhanging arm. The upper blade is actuated from alever 15, which in turn is oscillated by an eccentric on the main shaftbeneath the work support.

' The trimmer blades are located well in advance of the stitchingmechanism, so as to give room for the leading end of a bind ing stripbetween the point of trimming and the point of stitching.

Referring more particularly to Figs. 2 and 6, it will be noted that thework support 6 is provided with a throat plate 16 which is formed withfeed slots 17 and a needle throat 18, which indicates the stitchingpoint. The trimming members 10 and 11 are well in advance of the needlethroat 18. A binder 19, which is of the usual English type, is disposedso that its delivery end is between the trimming members 10 and 11 andthe needle throat 18, so that the binding strip passing through thebinder is mverted and delivered to the edge of the material, so as toextend on to the upper and lower faces of the material, and the needlepasses through the free edges of the bindmg strip, securing the same tothe material.

'The binder 19 consists of a body portion having the side edges 20 and21 so shaped as to fold the binding strip about the fingers 22 and 23.The delivery end of the binder is cut at an angle, so that said stripmay be inverted and led from the binder in a direction substantially atright angles'to the lonv gitudinal axis of'the binder. The strip as itpasses into the binder is led in rear of the shank 24: carrying thefingers 22 and 23.

The binder, as clearlv shown in the drawing, is curved at its deliveryend so that the strip may be led into the binder in a direction from therear of the machine, and as it travels through the binder it will becarried to the trimmed edge of the fabric in a direction at right anglesthereto. This binder is supported by a bracket 25, which is adjustablysecured to a bar 26, pivoted to a shank 27. The shank 27 is mounted in alug 28, attached to the work support, and said shank is held therein bya screw 29. The bar 26 is pivotally attached to the shank 27 by a screw30. The shank 27 is provided with a spring-pressed pin 31, see Fig. 5,which is adapted to engage a recess in the under face of the bar 26, andhold said bar 26 in the normal position shown in Fig. 3. The bracket 25is formed with slots 32,

through'which pass screws 33. These slots vertical direction, and serveas a means whereby the binder may be adjusted vertically, (that is, in aplanecuttingthe line of feed at right angles).'

From the above description, it' will be apparent that I have providedmeans for supporting the binder sothat it maybe adjusted vertically toposition'the same relative to the fabric being bound, and also adreadilyturned about the screw 30 as a pivot,

so as to move the binder from its" position adjacent the stitchingmechanism. This en'- ablcs the positioning of the binder so that it maybe readily threaded with the binding strip, and also aids in moving thebinder away from the looper or under thread-carrying elements, so thatthey may be easily accessible. r 7

As above noted, the binding strip is led from the rear of the machinethrough the binder. The shaft 12 supporting the upper trimming member iscarried the overhanging arm and is, therefore, raised a sufiicientdistance above the Iwork support so that the binding strip may bereadily led to the binder from the rear of the machine, without in anyway being interfered with by the parts of the trimming mechanism. As

a further means for guiding the binding strip to the binder, I haveprovided a guide 35, which directs the strip'to the binder. andfurtherprotects said strip from the moving parts of the feedingmechanisms and the trimmer-actuating mechanism.

In order to deflect the trimmed-0E strip away from the edge being bound,and also away from the stitching elements, I have provided the presserfoot 8 with a strip defiector 36. This strip deflector 36 is locateddirectly in rear of the trimming point, and projects beneath the worksupport.

A cover plate 37 is pivotally attached'at 38 to the bed plate, andprojects upwardly in front of the stitchingmechanism. This coverplate'at its upper end is curved as at 39, so as to extend in rear ofthe deflector 36 on the presser foot. The strip trimmed ofi' by thetrimming mechanism will be carried to the deflector and turned downagainst the cover plate, and this cover plate will serve as a furthermeans for guiding the the front of the machine, away from the op-.erating parts of the machine. The machine also is provided with abinder which is so disposed as to receive the binding strip from therear of the machine and direct the same to the edges of the fabric to becovered, after the fabric has been operated upon by the trimmingmechanism. This binder may be readily adjusted to various positionsrelative to the stitching mechanism and may also be readily swung fromoperative position. When the presser foot is raised, the cover plate 37may be readily swung about its pivotal support 38, so as to give accessto the under stitching elements.

It is obvious that minor changes in the details of construction and thearrangement of parts may be made, without departing from the spirit ofthe invention as set forth in the appended claims.

Having thus described my invention, what I claim as new and desire tosecure by Letters Patent, is
